To all whom, it may concern.-

Referring to the drawings, 1 represents part of the bolster of aoar-truck, 2 one of the axleboxes, and 3 a pair of the wheels. Each sideframe of the truck is made in diamond form and is cast in a single pieceof metal, except for a compression member, which is removably securedabove the bolster-opening of the frame.
